EDGE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No, 285,303, datedSeptember 18,1883.

Application filed January 19, l8ii3. (No model.)

T aZZ 2071/0/12 it may concern.-

Be it known that I, Enos PATTEN, of Lynn, in the county of Essex andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Edge-Setting Machines, of which theffollowing, taken inconnection with the accompanying drawings, is a specification.

This invention relates to that class of machines commonly used for thepurpose of burnishing the edges of boot and shoe soles and heels.

The invention consists in the details of construction and in thearrangement of the varirious parts, as will now be fully described andspecifically claimed.

In the accompanying drawings, Figure 1 gives a perspective side view ofa machine embodying my invention. Fig. 2 is a front view of thetool-bearing head and its component parts, while Fig. 3 illustrates themethod of attaching the tool toits carrying-shaft.

The shaft A is supportedby and adapted to turn in the frame-work B. Itis provided with a pulley, (not shown) to receive the drivingpower ofthe machine applied in the usual and obvious way, and it is alsoprovided with a fixed pulley, O. Said pulley O is connected by suitablebelt, a, to a pulley (not shown) on the shaft D, which shaft D isarranged to turn, as represented, in the frame E, and said frame E isarranged upon and supported by a second 'frame, F, which in its turn ismounted on the shaft A, so as to permit of being tipped or oscillatedthereon. Said frames E and F are connected together by means of aswivel-pin, I), so as to allow the frame E to be turned slightly inreference to frame F, while a counter-weight 011 thebottom end of frameFservesto keep the same in a nearly vertical position normally.

So much of the machine as is thus far described is found in thosemachines heretofore in use, and is not therefore of my invention;

stiffness and lack of flexibility in the movements thereof. The effortwas made to avoid this by using in place. of the belt a jointed metallicarm-connection, reaching from the shaft D to the tool or tool-bearingshaft in the head. This resulted in a machine having less vibration andjar in, the head, but which must necessarily be worked at a less rate ofspeed on account of the wear and liability to break the jointedarm-connections. To construct a machine having all the desirablefeatures of these two styles of construction, and at the same time toobviate the undesirable qualities there of, is the main object of thismy present improvement. To that end I locate the toolbearing shafte in asuitable head having a rearwardly-extending arm, f, and in the rear endof said arm f is a shaft, 71 carrying pulley m. Said shaft is furtherprovided with an ordinary eccentric and pitman-rod, 1-. The opposite endof the pitman r is connected to pin s, which projects into thetool-bearing shaft 6. Motion is transmitted from the pulley d to theshaft h by means of belt I, and from this shaft 71/ motion istransmitted through the pitman 9' and pin 8 to the toolbearing shaft 6,so as to oscillate in its bearings while the shaft h re.- volves.

The tool-bearing head is connected to its supportingarm H by means ofpin joint R, and permits of being slightly turned to either side in anobvious manner. fore end of the tool-bearing head is a rod, T, adaptedto reach forward and bear against the arm of the operator while he holdsthe handle 3, and so assists the workman to steady and manipulate themachine. The supporting- Attached to the arm H is suspended at its rearend from the 6. The inner ends of said latches are pivoted.

to the shaft 6, while their outer ends project slightly beyond the endof the shaft. The spiral spring 7, arranged, as represented, between thelatches, operates to open or expand their outer ends, as in Fig. 8, tohold the burnisliertool 2.

The burnisher-tool 2 consists of a small inetallic button having itsworking-faces shaped in the usual manner, and is provided with a centrallongitudinal bore, to receive the end of the shaft 0. The tool, whenslipped onto the end of the shaft 6, is retained in position by thelatches 6 6, as shown in Fig. 3. The hole in the tool for receivingtheshaft e is made tapering, its inner end being larger than the shaft0, so as to permit of certain loose motion, so as to adapt itself whilein operation to the curves and inequalities of the sole-edge.

The operation of the machine is similar to those now in use, and will beobvious to those skilled in the art.

I claim and desire to secure by Letters Patent 1. The combination of theshaft 6, latches G 6, suitable means to expand or open the said latches,and the burnishing-tool 2, all substantially as described.

2. The combination, with the shaft 6, of the burnisher-tool 2, havingthe conical base, whereby it is loosely mounted upon its shaft, for thepurpose set forth.

In testimony whereof I have signed this specification.
